Nearly 60 percent of American adults may have hypertension, or may be on the verge of suffering the condition, as measured by recently revised high blood pressure classifications.
The finding, reported in the Oct. 25 issue of the Archives of Internal Medicine, comes from nationally representative health data analyzed by two University of Illinois at Chicago researchers. Youfa Wang, an assistant professor of human nutrition and Qiong Joanna Wang, a biostatistician at UIC’s School of Public Health, analyzed data collected for the Centers for Disease Control and Prevention’s 1999-2000 National Health and Nutrition Examination Survey.
The Wangs found that more than half of all adults surveyed (58.2 percent) had blood pressure readings that placed them into the categories of either hypertension or prehypertension, a new, lower-threshold designation set last year in the Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation and Treatment of High Blood Pressure, known as JNC7. Prehypertension is indicated by systolic/diastolic readings of between 120/80 and 139/89. If either the systolic or diastolic blood pressure falls within this range, it indicates prehypertension. Hypertension remains defined as 140/90 or above in the JNC7 classifications.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
